Berkshire Hathaway Inc. (BRK.B), a giant conglomerate and one of the world’s largest companies, was founded by its current chair and CEO, billionaire Warren Buffett. Originally created by the 1955 merger of two New England textile manufacturers, Buffett acquired Berkshire Hathaway in 1965. It is now a holding company for the many acquisitions and investments Buffett has made over the decades.
With a market capitalization of over $1 trillion, it’s one of the largest publicly traded companies in the world, and one of the top ten companies in the S&P 500. Berkshire Hathaway’s diverse group of businesses generated a total of $371.43 billion in revenue in 2024 and $89 billion in net earnings attributable to Berkshire Hathaway shareholders.
Buffett, regarded as one of the world’s most successful investors, sold the textile business in 1985. He went on to acquire a broad range of companies in industries such as insurance, railroads, manufacturing, gas and electric utilities, and logistics.
Buffett has said he likes to invest in companies with an “economic moat,” meaning corporations that possess a sustainable competitive advantage enabling them to protect their business from rivals. For example, railroads and utilities have a moat due to the huge startup capital needed to lay railroad tracks or set up power lines. Some manufacturers, such as Precision Castparts (see below) have a large number of sophisticated and specific products that can be difficult to replicate, another form of a moat. Insurance is special because it involves one of Buffett’s major innovations, the use of insurance float as investment capital.
Warren Buffett’s unofficial successor will be Greg Abel, CEO of Berkshire Hathaway Energy and vice chair in charge of noninsurance operations, according to an announcement from vice chair Charlie Munger on May 1, 2021. It was announced on May 5, 2025 that Abel would take over the company as Chief Executive Officer on January 1, 2026. Buffett will remain as Board Chair.
Below, we look in detail at five of the company’s biggest acquisitions. In addition, we list the top five holdings in Berkshire’s $271.59 billion stock portfolio, which Buffett considers to be partial acquisitions.
GEICO
- Type of Business: Insurance
- Acquisition Cost: $2.3 billion
- Acquisition Date: January 2, 1996
- Revenue (FY 2024): $42.3 billion
- Earnings Before Taxes (FY 2024): $7.8 billion
GEICO, the acronym for “Government Employees Insurance Company,” originally served federal employees and the military. GEICO had a competitive advantage by being the first major insurer to market directly to customers. Warren Buffett purchased about half of GEICO’s stock over the course of a few decades leading up to 1996, when he purchased the remaining half of the company. GEICO was just one of Buffett’s insurance deals, as he first purchased National Indemnity in 1967.
Because insurance premiums are collected up front, and only paid out when and if something happens, insurance companies hold on to a huge amount of money to cover future payouts. Buffett has used this “insurance float” to make major investments, which is one of the keys to his success. The total float for all Berkshire’s insurance businesses was $171 billion dollars as of the end of 2024.
Burlington Northern Santa Fe Corporation (BNSF)
- Type of Business: Freight Railroad
